Abstract

A painting by A. Jorn on masonite board was badly damaged by fire. It was impregnated from the back with an acrylic binder by means of vacuum. The blisters were then laid using a vacuum hot-table at 75°C, the introduced acrylic acting as adhesive.  相似文献

Abstract

The condition before treatment and the subsequent consolidation of the wooden parts of an eighteenth century English fire engine are described. Experiments on a range of possible consolidants are outlined, and the application of polyvinyl butyral (Butvar B90, Monsanto) by both brushing and vacuum methods is presented. A closing discussion examines the relationship of the experimental findings to the practical application, the need for consolidation, and the final results of the treatment.  相似文献

Abstract

Problems were encountered when preparing objects from the Pacific islands for exhibition. These specimens were of wood with shell inlay. Cleaning with non-ionic detergent and distilled water had no effect on the dull shell surface; solvents were little better;finally, glass fibre brushes were tried with very good results. Precautions should be taken when using glass fibre brushes; these include the wearing of protective gloves, dust masks, and the provision of a vacuum cleaner to remove fragments of broken glass fibre and dust from the shell surface.  相似文献

Abstract

The study of the structure and materials of ancient works of art has been much intensified with the development and use of improved analytical techniques. It was considered desirable to apply an X-ray fluorescence technique which could scan polished cross-sections of paint materials embedded in plastic. Layer thicknesses of 20–50 μ were successfully surveyed with an X-ray macroprobe attached to a fine-focus vacuum X-ray spectrograph. Elements above atomic number 16 in areas of 50 μ diameter were successfully detected and precisely located in the cross-section. The method has been applied particularly to the study of the technique of Rembrandt and Lievens paintings.  相似文献

Abstract

Wood, particularly in the presence of excessive moisture, deteriorates due to action of biological agents and sunlight. Decay manifests itself not only in impairment of physical strength but also in discoloration. Protection of the paint during consolidation by impregnation and polymerization, albeit difficult, is possible. Details of a home-built 23 cm-diameter and 48 cm-long chamber for vacuum impregnation are given. The permeating methylmethacrylate monomer solution used with good results contained bis-4-t-butylcyclohexyl peroxidicarbonate as catalyst, and pyridine as activator in addition to methylmethacrylate polymer, which reduced the rate of heat generation by the reaction. Polymerization induced by gamma irradiation also yielded satisfactory results. Case histories of three artifacts are described.  相似文献

ABSTRACT

This paper reports on findings from an exploratory investigation about parents’ perceived role of the Facebook Like in sharenting (i.e., sharing about their children on social media) by drawing on the qualitative results of an online survey. Findings show that the majority of participants think that getting a Like on a picture of one’s child can encourage a parent to share more about him/her because of two main understandings of this paralinguistic cue: the Like as a received validation of one’s parenting, or as a metric of connection with important people, causing emotional reactions in the receivers. Several parents, though, judge the Like as more commonly being important for others, explaining this difference in terms of internal characteristics. This study aims to extend our understanding of the motivations behind sharenting by taking into account the role of the Like in this practice and highlighting how parents position themselves in such an exchange of digital photo-sharing and feedback. As communication does not happen in a vacuum, we advance that research on parents’ photo-sharing behavior online may benefit from considering whether and how social media liking can foster and shape interpersonal communication between posters and recipients.  相似文献

Objective: This study was undertaken in order to determine how health sciences libraries in a ten-state region are using Loansome Doc, with an emphasis on whether this tool continues to be used to serve unaffiliated health professionals. Methods: Usage data were examined and health sciences libraries were administered a survey to determine how they are using this tool. Results: Loansome Doc usage across libraries is low and declining, and a number of libraries do not serve unaffiliated health professionals with this tool. Conclusions: Use of Loansome Doc is low and declining, in part, due to license restrictions, declining interlibrary loan, and the prevalence of alternatives, such as OCLC's ILLiad, for document delivery to affiliated users.  相似文献

ABSTRACT

Purpose: The present study aims to determine and compare the views of directors and users of public libraries on the use of social media for the marketing of library services.

Methodology: Data collection was done through two researcher-made questionnaires, one from the viewpoints of directors and one investigating the views of users. The questionnaires’ validity was done by four libraries and Information Science professionals, and the reliability was determined by the Cronbach’s alpha coefficient. The statistical population of this research is made up of all directors and users of 12 public libraries of the city of Isfahan, one of the largest cities in Iran.

Findings: In users’ viewpoints, the “interaction capability” is the most important feature that social media marketing can have in libraries. From the viewpoints of the directors, “creating a true picture of the role of the library” and “informing users about library services” are among the most important reasons for the marketing of libraries in the social media. From the perspective of both groups, the Telegram is the most appropriate medium for the marketing of library services.

Results: To maintain their customers and their market position, libraries need to use more exciting tools such as social media for marketing. Library directors of this study emphasized on this fact and 79.1% of users expressed interest in receiving library information through social media.

Value: The findings of this study would help the library directors to better decide on the marketing of their library services in social media.

Type of the study: Scientific-Research  相似文献
